Hello,
We found cracks in gas manifold in W20V31SG motors. Five motors are installed in power station with around 8000 operating hours. These cracks appear at 4000 hs. Cracks were indicated in weld areas and most of them around manifold supports. Change out of damage manifold was made.
Gas manifold is a square section.
Could you please share with me information about this issue?
Best regards.
